In an elastic head-on collision, a 0.60 kg cart moving at 5.0 m/s (W) collides with a 0.80 kg cart moving at 2.0m/s (E). the collision is cushioned by a spring (k=1200 N/m)
a find the velocity of each cart after the collision
b find the maximum compression of the spring
ATTEMPT:
cart 1:
v1=( m1-m2/m1+m2)(v1)
v1= (0.6-0.8/0.6+0.8)(7)
v1= -1
then i did -1 + -1 = -3 m/s (E)
cart 2:
v2= (2m1/m1+m2) (v1)
v2= 6
6 + -2= 4 m/s (W)
i'm totally lost for part b
